Title: Diversity radio equipment
Inventor: IWAHASHI KOJI
IPC: H04B7/08
Filed: 1985-03-01
Abstract: PURPOSE:To attain light weight and small size when the titled equipment is used as a portable radio equipment not requiring diversity by connecting a high frequency filter and a changeover switch via a high frequency amplifier section so as to attain ease of impedance matching. CONSTITUTION:Since a changeover switch 7 is connected to a high frequency filter via high frequency amplifier sections 5, 6, the impedancematching is very easier in comparison with a conventional system where the changeover switch is connected directly to the high frequency filter and no tight matching is required. Since an antenna 1, a high frequency filter 3, the high frequency amplifier section 5 and a changeover switch 7 are used independently as an auxiliary radio section, that is since the diversity function is separated as a unit, when the equipment is used as a radio equipment not requiring diversity such as a portable radio equipment, the unit for diversity function, that is, the auxiliary radio section is used separately.

Abstract: PURPOSE:To produce a belleville spring which has good wear resistance and slip characteristic and good durability by tempering a spring material having a prescribed shape after hardening at the tempering temp. or below in a vacuum chamber and simultaneously forming a titanium nitride layer by vapor deposition on the surface thereof. CONSTITUTION:The spring material which is molded to a desired belleville spring shape is hardened and rapidly cooled. This spring material after the hardening is put into a vacuum furnace and is tempered by heating to about 450-500 deg.C tempering temp. Titanium is evaporated by heating in the furnace simultaneously therewith and a reaction gas contg. nitrogen and an inert gas are introduced into the furnace. The evaporated titanium reacts to form the titanium nitride and the titanium nitride layer which is thin and hard and has high adhesiveness is formed by vapor deposition on the surface of the spring material. The belleville spring which does not generate fretting and worn powder against inter-plate friction and does not adversely affect peripheral mechanical elements is thereby obtd.

Title: Digital signal recording system
Inventor: ADACHI OSAMU
IPC: G11B20/14
Filed: 1984-03-05
Abstract: PURPOSE:To attain synchronization detection resistive to a bit slip by arranging a buffer part in the front or back of a dispersedly inserted synchronizing signal, allowing the width of a detecting window for the synchronizing signal to be expanded when synchronization detection is applied to the read-out data. CONSTITUTION:Plural sectors are arrayed in series on an optical disc, data are recorded in respective sectors and the front and back of each sector are divided by gaps 21. A preamble 20a for leading bit synchronization, sector synchronization 20b, buffer part 20g, sector address 20c, and a gap 20d are successively formed in a sector following the gap 21, then a data part is recorded. Since the sector synchronization 20b is formed as a pattern having sharp self-correlation and the preamble 20a is constituted of simply repeated patterns having minimum inversion intervals, a detecting window can be expanded to the front of the synchronization 20b. The detecting window can be expanded also to the buffer part 20g arranged on the back of the sector synchronization 20b. Thus, synchronization detection resistive to a bit slip can be attained and stable signal reproducing can be performed.
